This article argues that if the U.S. took away the mortgage interest tax deduction, it could provide a housing voucher to everyone below the median household income. That’s hard to believe, but the key is probably that the median is well below the average, because of course the income distribution is skewed toward the top. I like my mortgage interest deduction. It is an important part of my retirement strategy and as I am a bit above the median (but hardly rich) it would be hard for me to support this policy.
Here’s another article on BillMoyers.com that says if you took away the mortgage interest tax deduction, the cap on social security deductions, the lower rate on capital gains, and tax-advantaged retirement accounts, you could double Social Security benefits for everyone. There’s a bit of a trick here – these ideas are presented as revenue neutral, because you can think of all these tax breaks as money the government is spending, rather than money it is not collecting compared to what it could be collecting or what it has collected under some past policy. It would be very easy to paint these as tax increases instead, of course. Still, I could be more easily persuaded to support this policy that the first one, because I would be guaranteed to get a portion of the higher taxes I am paying now back when I am older, and I wouldn’t have to worry so much about savings or home equity now. I would know that people who are both richer and poorer than me would all get the same share I would get, which I might be able to accept on grounds of fairness. I’m not out in the streets campaigning for this policy yet, I have to think about it.
